Abstract

Obtaining means obtains acceleration data from an input device. Swing detection means detects a swing of the input device in a real space when an acceleration represented by the acceleration data satisfies a predetermined condition. Type determination means determines a type of swing of the input device in the real space by using an acceleration in a predetermined axial direction among all the accelerations represented by the acceleration data obtained by the obtaining means after the detection by the swing detection means. Object moving means moves a predetermined object in a virtual game space according to the type determined by the type determination means. Display control means displays the virtual game space with the object therein on a display device.
